I have a dataframe with groups.
To normalize the values for each group I'd like to divide all values of each group by the value of a certain element within that group.
df = pd.DataFrame([['a','2018-02-03',42],
['a','2018-02-04',22],
['a','2018-02-05',10],
['a','2018-02-06',32],
['b','2018-02-03',10...

This is a fairly simple question, yet I am struggling to find an elegant solution for!
Suppose you want to iterate from 0.0 to 1.0 in discrete steps, you'll use a for loop that uses int since it's discouraged to use float due to precision errors.
The simplest approach is the following but it's flawe...

I need to standardize all except one column in a dataframe, with which I'm using knn. I know that I can do this with loops, but it seems like there might be an easier way, especially since I am working with 200+ columns/factors, which would have to be renamed.
Any suggestions?

I have a large m *n sparse matrix Y. I would like to normalize each row of Y, so that each row has zero mean.
I first tried this. But the mean of each row is also subtracted from the zero entries, which is not what I want.
Ynorm = bsxfun(@minus, Y, Ymean);
Then I tried this.
[m, n] = size(Y);
